For developers of Apple app developers, there is a significant update which the company shared on the official Apple Developer site. The company mentioned an update that all 32-bit Mac apps won’t be accepted after 31st December 2017.
This reports after the year 2017 all the new apps submitted to the Mac App Store must support 64-bit of architecture. Now you might be thinking that what about pre-existing 32-bit apps? For that Apple gave a deadline of June 208 before which all the apps should be upgraded to 64-bit.
According to Apple, the upgrade is much needed as a matter of the fact that macOS High Sierra will be the last macOS release to support 32-bit architecture. Similar to that iOS 11 was the last one to defend 32-bit mobile apps and the same is now happening with macOS.
The upgrade is a successive one and will help users to get an upgraded variant which will undoubtedly perform better than the previous one.
On December 1, 2017, the company updated its developer site with news which is mentioned below. The report was entitled to “64-bit Requirement for Mac Apps.
As a reminder, new apps submitted to the Mac App Store must support 64-bit starting January 2018, and Mac app updates and existing apps must support 64-bit starting June 2018. If you distribute your apps outside the Mac App Store, we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS. The last macOS release to support 32-bit apps without compromise is macOS High Sierra.
As Apple is upgrading its devices with much more advanced operating systems thus this updation of Mac apps is necessary.
